At least get some Milkies so you can save the leakage & freeze it. Be careful w/ the pumping. If you're sensitive to nipple stimulation it can trigger early labor, so watch yourself and if you feel crampy at all, stop. Stay in touch with your doc.

That being said, I really wish I had saved the leaks & at least tried a little pumping... I wouldn't have been so frantic when my boy went on a 2 week nursing strike.

Probably not a good idea as you are still not far along. Plus the milk you are producing now is tailored to the baby you are pregnant with now, which means it will not be nutritionally tailored to a 7 month old...wouldn't do him any harm but doubt he'll accept the taste.
